Whether or not she started out as a nice person, I'd have an impossible time continuing to think favorably of anyone (much less continue to call that person a friend) who would put his/her desire to make money as more important than the survival of my unborn child.

For me, the whole "kidnapping people to take them to a sales event" is what really stands out from Sandra's past. Someone might say something obliviously hurtful in a non-thinking moment, or just be caught up in their enthusiasm for something and not understand how they're being perceived by others, resulting in her comments to the OP (which are nonetheless painful). But the planning and deception involved in telling people they were going to dinner, then insisting on driving them and changing the destination to a sales party? To me that is deliberate and malicious, and nothing less than a complete about-face, abject apology, and visible change in behavior would make me even consider being friends with that person again.

For this and for the heartlessness she has shown the OP, I advise completely dropping her. For the moment, at least--if you don't feel comfortable saying "forever," perhaps decide you're not going to have anything to do with Sandra until your health crisis has passed and you can afford to think about other things again. I would block her on every avenue and ignore any further communication attempts. She's a source of unneeded stress right now and I don't think it would be rude to mute that for the time being, given her behavior.

On a side note, without meaning to derail the thread: I've known a number of people who've been successful with MLMs like Mary Kay, and have never gotten so caught up in it as to be rude. In my observation, the people who are both successful and polite are those who are business savvy and perhaps already have some business experience before they begin the MLM, like women who run their own hair salon and sell MK at the counter. And then there was my friend who got sucked into MK after a bad break-up, spent thousands of dollars on product at once, and was irritated that the co-workers she invited to parties didn't show enough enthusiasm. I think it really depends on the individual, whether they're prone to rudeness or not.

A polite person, on hearing that someone is experiencing a medical issue, express their concern, their wishes for a happy outcome, and their understanding that of course, social engagements are not possible at this time.

A really nice person also inquires if Tuesday or Thursday would be the best night to drop off a casserole and the rest of the fixings for a meal, or sends flowers, or a "thinking of you" card, or offers to babysit or drive someone to an appointment.

Update on my condition: everyone's thoughts and prayers worked! Things are looking much better in my last ultrasound scan, which is such a huge difference from the week before that when the prognosis was quite depressing. So thank you very much!!

I have stopped bleeding heavily, but I am still on medication and bed rest until the end of the month. I remain at high risk for preterm labour and am still a long way from 24 weeks, so my doctor is being cautious for now. We are keeping our hopes and prayers that we will get there.

As for Sandra, I have not heard anything from her. That would most likely be because I have unfriended her on Facebook and removed her from my Skype contact list. Sometimes bed rest can be tooo peaceful (and boring), but having Sandra around right now is way too much drama!

I haven't posted much recently, Nemesis, but I just wanted to let you know that I think you handled the whole event very well, and that I am sending trans-Atlantic good thoughts to you and the little one (and indeed the rest of your family). I hope everything continues to improve for you.
